India Quarter Anna 1907 with reverse brockage error

WillieBoyd2

This British India quarter anna appears to have a brockage error on the reverse:

British India Quarter Anna 1907
Bronze, 25 mm, 4.83 gm, Krause KM 502

The mirror image of the king's head appears on the reverse with the king's nose to the left.

Any comments or alternate ideas for the lines on the reverse?

I think it's more likely to be clash marks. The dies came together without a planchet between them and struck each other, leaving a reversed impression of the obverse on the reverse die. Coins subsequently struck from the dies show the traces of the clashing left in the reverse die.

With brockage, a coin sticks to one of the dies as it is struck. The stuck coin then gets impressed in one side of the next blank to be struck, leaving a complete reversed image of the opposite die from the one with the coin stuck to it. No trace of the design from the die the first coin is stuck to appears on the second, because the stuck coin completely blocks that die from contacting the second coin that gets the brockage strike.

Yes it's clashing as Titus explained.

Nice coin, by the way! I like Edward VII coinage, but haven't seen much of his Indian issues.

I concur with @TitusFlavius that it's a die clash. Nice find. Peace Roy

Thank you for the information.

By the way, I have had this coin since 1965 when I was a teenager and found it in a coin dealer's foreign coin box.
